The original Pentium processor was a 32-bit microprocessor produced by Intel. The first superscalar x86 architecture processor,it was introduced on March 22, 1993. Its microarchitecture (sometimes called P5) was a direct extension of the 80486 architecture with dual integer pipelines, a faster FPU, wider data bus, and features for further reduced address calculation latency. In 1996, the Pentium MMX was introduced with the same basic microarchitecture complemented with MMX instructions, larger caches, and some other enhancements.

The name Pentium was derived from the Greek pente, meaning ‘five’, and the Latin ending -ium, a name selected after courts had disallowed trademarking of number-based names like “i586″ or “80586″. In 1995, Intel started to employ the registered Pentium trademark also for x86 processors with radically different microarchitectures (Pentium Pro / II / III / 4 / D / M).
